Public methods

beginUniqueWork

Added in 2.5.0
public abstract @NonNull RemoteWorkContinuation beginUniqueWork(
    @NonNull String uniqueWorkName,
    @NonNull ExistingWorkPolicy existingWorkPolicy,
    @NonNull List<OneTimeWorkRequest> work
)

This method allows you to begin unique chains of work for situations where you only want one chain with a given name to be active at a time. For example, you may only want one sync operation to be active. If there is one pending, you can choose to let it run or replace it with your new work.

The uniqueWorkName uniquely identifies this set of work.

If this method determines that new work should be enqueued and run, all records of previous work with uniqueWorkName will be pruned. If this method determines that new work should NOT be run, then the entire chain will be considered a no-op.

If any work in the chain fails or is cancelled, all of its dependent work inherits that state and will never run. This is particularly important if you are using APPEND as your ExistingWorkPolicy.

Parameters
@NonNull String uniqueWorkName

A unique name which for this chain of work

@NonNull ExistingWorkPolicy existingWorkPolicy

An ExistingWorkPolicy; see below for more information

@NonNull List<OneTimeWorkRequest> work

One or more OneTimeWorkRequest to enqueue. REPLACE ensures that if there is pending work labelled with uniqueWorkName, it will be cancelled and the new work will run. KEEP will run the new sequence of work only if there is no pending work labelled with uniqueWorkName. APPEND will create a new sequence of work if there is no existing work with uniqueWorkName; otherwise, work will be added as a child of all leaf nodes labelled with uniqueWorkName.

Returns
@NonNull RemoteWorkContinuation

A RemoteWorkContinuation that allows further chaining

cancelAllWork

Added in 2.5.0
public abstract @NonNull ListenableFuture<VoidcancelAllWork()

cancelAllWorkByTag

Added in 2.5.0
public abstract @NonNull ListenableFuture<VoidcancelAllWorkByTag(@NonNull String tag)

Parameters
@NonNull String tag

The tag used to identify the work

Returns
@NonNull ListenableFuture<Void>

An ListenableFuture that can be used to determine when the cancelAllWorkByTag has completed

cancelUniqueWork
